[sdiy] Typical ESR of different capacitors

[Tom Wiltshire]

How about getting one of these and testing a few?

That provided some help, but unfortunately the table and figure are flawed as they use different frequencies for the measurements and assume ESR is constant over frequency (which it isn't due to dissipation factor as far as I've been able to understand). Almost all the data I found seemed to assume that normal electrolytics would only ever be used as main PSU filter caps and never for any further filtering where higher frequencies were important.
